Does it pay to care? Volunteering and employment opportunities

We investigate whether volunteering has a causal effect on individual employment opportunities. To this end, a field experiment is conducted in which volunteering activities are randomly assigned to fictitious job applications sent to genuine vacancies in Belgium. We find that volunteers are 7.3 percentage points more likely to get a positive reaction to their job applications. The volunteering premium is higher for females but invariant with respect to the number of engagements.     

Logratio approach to statistical analysis of 2×2 compositional tables

Compositional tables represent a continuous counterpart to well-known contingency tables. Their cells contain quantitatively expressed relative contributions of a whole, carrying exclusively relative information and are popularly represented in proportions or percentages. The resulting factors, corresponding to rows and columns of the table, can be inspected similarly as with contingency tables, e.g. for their mutual independent behaviour. The nature of compositional tables requires a specific geometrical treatment, represented by the Aitchison geometry on the simplex. The properties of the Aitchison geometry allow a decomposition of the original table into its independent and interactive parts. Moreover, the specific case of 2×2 compositional tables allows the construction of easily interpretable orthonormal coordinates (resulting from the isometric logratio transformation) for the original table and its decompositions. Consequently, for a sample of compositional tables both explorative statistical analysis like graphical inspection of the independent and interactive parts or any statistical inference (odds-ratio-like testing of independence) can be performed. Theoretical advancements of the presented approach are demonstrated using two economic applications.     

Verlustnutzung von Kapitalgesellschaften bei Umwandlungen – Eine ökonomische Vorteilhaftigkeitsanalyse

This paper investigates the potential utilization of tax loss carry-forwards in case of reorganizations of corporations from an economic point of view. Thereby, we analyze the tax impacts of indirect utilizations of tax loss carry-forwards by means of increasing assets’ book values as well as the tax impacts of the minimum taxation. The paper illustrates that the implementation of minimum taxation on transfer gains – which is reasonable at first glance – results in the following effects: Contrary to assumptions made in literature, the consequence of the regulation is that no reorganization can be utilized in order to avoid minimum taxation of current earnings in a profitable way. Surprisingly, for reorganizations due to other intentions it may be economically reasonable to let tax loss carry-forwards lapse at least partially. From an economic viewpoint this is in breach of the objective net principle.     

证人出庭与刑事被告人对质权的保障(英文)

刑事证人出庭作证的主要意义在于保障被告人的对质权。因此,刑事证人出庭问题基本上可替换为以被告人对质权为核心的必要证人出庭问题。由于中国的刑事诉讼法及其司法解释并未赋予被告人对质权,实践中必要证人出庭率仅为25%左右。这种无对质权语境下的刑事审判,通常表现为积极的实体真实主义、定罪量刑的非精细化操作和裁判正当性来源的单一化。为改变这一局面,有必要确立对质权制度及相应的保障机制。     

In the Long Run We Are all Dead: Hey Keynes, What Is Long in the Contemporary US Case?

The idea of declinism of the US had emerged in every decade after the World War Two and so it was as well after the end of the Cold War. The article argues that such a phenomenon may be attributed to the nature of the international system, where through the globalization the US enables ‘the rest’ to grow on its expense. China and other export led economies, made great benefit of the US open market that is functioning as a ‘big vacuum cleaner’. The focal question of article is two-folded: first, is ‘the raise of the rest’ causing the geoeconomic centre of power to shift from the Atlantic to Pacific; second, is the US in decline? Article presents economic data that show that there are no economic incentives for the geoeconomic shift. The geopolitical centre may indeed by shifting, but not due to the geoeconomic reasons, but rather due to military, political, and ideological power factors. The US has been in relative decline since the end of the WW2—other international actors seized the chance that the international system created by the US provided. Thus, the relevant question about declinism is—is the US in absolute decline? The article argues that the 2008 financial shock was not cyclical in nature, but rather systemic. It is the first time since the WW2 that the US was unable to answer to the challenge adequately. The main reason for that is not external, namely, the relative decline of the US—G8 was replaced by G20—but internal—the US is not tackling the core of its systemic economic problem. This suggests that the US is marching towards an absolute decline. To avoid its demise, the US has to change its Keynesian pragmatic short-sighted economic mentality and do the well needed structural reforms.
